SOAP-BUBBLE PIPE.

SPECIFICATION forming part of Letters Patent No. 657,791, dated September 11, 1900.

Application filed January 27, 1899. Serial No. 703,550. KNo model.)

To all whom, it may concern.-

Be it known that I, CHARLES SOHINDLER, a citizen of the United States, residing at T0- ledo, Lucas county, Ohio, have invented certain new and useful Improvements in Soap- B u hble Pipes,of which the following is a specification.

' My invention relates to devices for blowing soap-bubbles; and the object of myinvention is to provide a simple device of this character which can be employed without necessitating the preliminary making of a soap solution. I accomplish this result by means of the device hereinafter described, and shown and illustrated in the accompanying drawings, made part hereof, and in which- Figure 1 is a central longitudinal sectional elevation of my device complete. Fig. 2 is a perspective view of the soap tablet hereinafter referred to, and Fig. 3 the fastening device hereinafter referred to detached.

In the drawings, a is the cylindrical bowl. Connected with the closed end of the bowl is a tubular stem 1), the bowl of which is connected with the cavity of the bowl a.

c is the soap tablet, specially formed to closely fit the cavity of the bowl. Axially through the tablet is a small opening d, which coincides with and forms an extension of the passage in the stem b. Means may be employed for securing the tablet in place, consisting, preferably, of aspring 6, adapted to be forced into the inner end of the stem 19 and having at its outer end one or more hooks Or claws f to engage the tablet. The resiliency of the spring holds it in place within the stem, and the hook or claw prevents the tablet from slipping out of the cavity of the bowl. It will be seen that the tablet may be removed at will and that a new tablet may be supplied whenever desired. The spring e or its equivalent is not essential, however, as the tablets are made of a size which will closely fit the smooth cylindrical walls of the bowl, and as the wearing away of the tablet is entirely internal--that is, from the opening (Z outward and over the exposed front end or face thereofthere is no such wearing of the tablet as will loosen it from the bowl.

In operation the bowl is simply dipped into water, resulting in the formation of a thin film or soap solution across the opening cl.

This opening being a small one and being in alinement with or coinciding with the passage in the stem 1) the forcing of air through the stem drives this film outward and causes it to spread out over the exposed end or face of the tablet, taking up some of the soap as it passes and forming a bubble of a size dependent upon the amount of air blown through the stem. The bubble always starts at the small opening in the center of the tablet, and the gradual wear of the tablet occurs at the front end of said opening and across the face of the tablet, thus enabling the device to be used until but a very small part of the tablet is left in the bowl, the last part of the tablet being generally located around the base or bottom of the bowl and reaching from the wall thereof to or nearly to the opening in the stem. The tablets are preferably furnished of the correct shape with the pipe, and a new one can be located in the bowl by simply pressing it therein, requiring no molding of the tablet.

The advantages of the device are mainly due to the fact that the bowl is cylindrical and has smooth inner walls, which enable one tablet to be readily substituted for another, and to the fact that the passage or opening through the tablet is small and in alinement with or coinciding with the air-passage in the stem.

I claim 1. A device for blowing soap-bubbles consisting of a cylindrical bowl having smooth inner walls, a stem connected with the cavity of the bowl, and a soap tablet conforming to the cavity of the bowl and having a small aperture therethrough coinciding with the bowltof the stem, substantially as described.

2. A device for blowing soap-bubbles consisting of a cylindrical bowl having smooth inner walls, a stem connected with the cavity of the bowl, a soap tablet conforming to the cavity of the bowl and having a small aperture therethrough coinciding with the bowl of the stem, and a spring adapted to aid in holding the tablet in the bowl, substantially as described.
